Answer:

138

Step-by-step explanation:

Use the symbols A for number of marbles Abdul has

D for number Durai has and M for number Mutha has, then

D + A = 328 , M + D = 176

Since A = 5M then D + 5M = 328

We now have 2 equations in D and M which we can solve

D + 5M = 328 → (1)

D + M = 176 → (2)

Subtract (2) from (1) term by term

(D - D ) + (5M - M ) = (328 - 176 )

4M = 152 ( divide both sides by 4 )

M = 38

substitute M = 38 into D + M = 176

D + 38 = 176 ( subtract 38 from both sides )

D = 138

Hence Durai has 138 marbles

We have opposite and hypotenuse making sin.

Length×Sin(Angle)

5×Sin(45) = 3.53553cm

Rounded the the nearest tenth makes 3.5cm

BC = 36; D = 15. What is the value of BD - AC. B A BD - AC =

Snezhnost [94]

Answer:

BD - AC = 0

Step-by-step explanation:

Given that:

BC = 36 , CD = 15 and BD = x

As these are forming right angled triangle,

Using Pythagorean theorem,

$(BD)^2+(CD)^2=x^2\\(36)^2+(15)^2 = x^2\\1296 + 225 = x^2\\1521 = x^2\\$

Taking square root on both sides

$\sqrt{x^2}=\sqrt{1521}\\x=39$

As the given shape is rectangular, the sides parallel to each other will have same values.

AB = 15 , AD = 36 and AC = x

$(15)^2+(36)^2 = x^2 \\225 + 1296 = x^2 \\1521 = x^2 \\x = 39$

Now,

BD - AC = 39 - 39 = 0

Hence,

BD - AC = 0
